摘要 [目的]研究福建地区龙眼花精油的主要化学成分。[方法]通过水蒸气蒸馏法对龙眼花精油成分进行提取,利用固相微萃取技术对样品进行采集,气相色谱-质谱(GC-MS)法和计算机谱库对样品成分进行分离分析,结合人工谱图解析对龙眼花精油成分进行鉴定。[结果]共检测出95种化学成分,通过面积归一化法确定了各化学成分的百分比含量,进一步归类得出:烷烃、烯烃类相对含量为42.35%,芳香烃40.30%,醇类13.05%,酯类0.61%,醛类0.36%,酮类0.25%。[结论]该研究结果为合理应用福建产龙眼花药材提供一定的科学依据。

Abstract [Objective]To study the main chemical components of the essential oil of longan flower in Fujian Province.[Method]The essential oil of longan flower was extracted by watersteaming method.Then samples were collected by solid phase micro extraction.The constituent was isolated by gas chromatographymass spectrometry(GCMS),and the constituent was analyzed by the computer spectral database(NIST/WILEY),finally the constituent was confirmed artificially referring to data.[Result]A total of 95 chemical components were detected,and the percentage content of each chemical component was determined by the area normalization method,which was further classified: the relative content of alkanes and olefins was 42.35%,aromatic hydrocarbons were 40.30%,alcohols 13.05 %,esters 0.61%,aldehydes 0.36%,ketones 0.25%.[Conclusion]The results of this study provide a certain scientific basis for the rational application of longan flower medicinal materials produced in Fujian.

龙眼是无患子科植物,在我国南部广泛种植,福建、台湾地区种植最多,广西、广东次之[1]。龙眼生产普遍存在“花而不实”的现象,龙眼花量大,授粉受精不良加上营养消耗多[2-3],导致小果前期发育不良而大量落花落果,因此龙眼生产中通过疏花来控制花量,提高着果率[4-5]。……
